![]() ![]() XTAL1,XTAL2: The crystal oscillator (16Mhz) is connected to the controller clock and is grounded through 2 bypass capacitors.ĪREF: Using this pin, when we use ADC for analog-to-digital conversion, use external reference voltage for conversion instead of reference voltage from internal 1.1V or 5v reference. Analog pins are labeled A followed by their number, they allow you to read analog values using the analog-to-digital converter (ADC) in the ATMega chip. The Arduino Mega has a built-in reset circuit, a key reset system, and can be used as a reset controller for other devices. It has 54 digital input/output pins (of which 14 can be used as PWM outputs), 16 analog inputs, 4 UARTs (hardware serial ports), a 16 MHz crystal oscillator, a USB connection, a power jack, an ICSP header, and a reset button. to store the values read from your sensor. Youll also create another variable, sensorValue. RESET: (Reset input) The low level of this pin exceeds 4 clock cycles and the board will reset. The Arduino Mega 2560 is a microcontroller board based on the ATmega2560 (datasheet). is set to to analog pin 0, where your potentiometer is attached, and. The Arduino Mega 2560 also adds features such as analog comparators, external and software interrupts, power save mode, built-in temperature sensor, RTC, and more. USB (Programming with ATmega 8), ICSP (programming), SPI, I2C and USART Arduino Mega 2560 Hardware Specifications Arduino Mega 2560 So for some more complex projects, this is an excellent choice. The Arduino Mega 2560 is a replacement for the older model Arduino Mega, so, it will be named the "2560" extension. Other features of the Arduino Mega 2560 include JTAG support for programming, debugging and troubleshooting large flash and SRAM that can easily handle bulky programs it is also compatible with different types of modules such as high-level (5V) or low-voltage Flat (3.3V) and I/O ref pins it supports ICSP and USB microcontroller programming on the PC side. There are more than 5 sets of Vcc and Gnd pins, which can easily connect other devices to the Arduino Mega 2560. By default they measure from ground to 5. ![]() Built-in RTC and other functions, such as analog comparator, advanced timer, controller wake-up mechanism interrupt, etc., 16MHz crystal clock can get 16 MIBS, and it saves power and is fast. The Mega has 16 analog inputs, each of which provide 10 bits of resolution (i.e. For example: it has built-in 16 analog sensors and 54 digital sensor interfaces, and supports USART and other communication modes. It has 54 digital input/output pins (of which 14 can be used as PWM outputs), 16 analog. Arduino Mega 2560 has many features that other boards do not have. The Arduino Mega is a microcontroller board based on the ATmega2560. Why choose Arduino Mega? The main reason is that this board is more convenient for expansion. There are cheaper Arduino boards on the market. ![]()
